Although these studies generated interest at EACS, many people reserved caution about the results.

These were all single arm pilot studies in small groups of people with short periods of follow-up.

They all concluded that results need to be confirmed in larger studies where follow up is just as close and where results are compared to using standard three drug treatment. The new studies will need to look into how effectively mono and dual therapy works in different body sits -- not just based on results from blood tests.

Nevertheless, for people struggling on current ART, the results offer great hope if the early promise is sustained.

For wider global access it is also significant that manufacturers ViiV Healthcare agreed to dolutegravir being available for generic manufacturers as part of the Patent Pool.13
